Laminated permanent magnet is a special designed magnetic assembly. By means of insulated stitching, multiple pieces of rare earth neodymium magnets or samarium cobalt magnets are spliced into one whole. For example, rare earth magnets are glued to each other or onto a steel plate with the same polarity across the entire stack.
This laminated rare earth magnet has small vortex. At the same time, the performance is as good as the overall magnetic component or even superior. It is primarily built for reducing Eddy Currents in motors that result in efficiency losses due to heat generated in the magnetic circuit.
Laminated magnets are the ideal solution for customers looking to get increased efficiency from their permanent magnet motor materials. It is a popular trend that aerospace, motorsport, automotive, and industrial markets are turning to laminated rare earth magnets.
